The intake air system provides clean air to the engine, optimizes airflow, and reduces unwanted induction noise. The intake air system consists of an air cleaner assembly, resonator assemblies and hoses. A flat air filter element provides maximum air filtration with minimum flow restriction. The main component of the air intake system is the air cleaner assembly. The air cleaner assembly houses the air cleaner element that removes potential engine contaminants, particularly abrasive types. The air cleaner housing and ducts are designed to allow the maximum airflow possible with a minimum of noise, and to reduce the potential for water ingestion into the engine.
If an engine maintenance procedure requires the temporary removal of the air cleaner, remove it; otherwise, never run the engine without it. The air filter should be replaced every 30,000 miles (50,000 km).
REMOVAL & INSTALLATION
Locate the air cleaner in the engine compartment. Inspect the flexible air intake ducting for cracks and tears. If the ducting is torn it should be replaced.
The air cleaner element may be replaced easily.
- Remove or disconnect the intake air temperature (IAT) sensor, if equipped and mounted in the air cleaner housing.
- Loosen the intake air duct clamp and remove the air duct as necessary.
- Disengage the fasteners securing the top of the air cleaner.
- Carefully tilt the air filter cover back to expose the element.
- Remove the air filter element.
- Wipe out the housing with a clean rag.
- Position the air filter element in the housing, make sure it seats properly.
- Install the air cleaner cover. Connect the intake air duct and tighten the clamp.
- Install the IAT sensor, if removed, or reconnect as necessary.
- Install the air cleaner fasteners, and tighten as necessary.
